Did you ever find a solution to this?

 

I just moved my fully functional website to a new server and have been getting this error as well.

On your admin back office, check your php version to see if your new server meet the requirement. If not, grade the version. And also, ask your host to clean up any vanish on your server, then wait and see!

Good luck!
